Detailed Description

AssemblyKernelBase abstracts the operations that must be done in an assembly loop.

Regardless of whether the assembly loop is doing matrix/vector fill, vector fill, functional/gradient evaluation, or functional evaluation, the assembly loop will involve

A preprocessing step before the main assembly loop
A preprocessing step before each work set is started
A fill step after each integral group is done
A postprocessing step after the main assembly loop is done

The first of these is done by the subclass constructor. The others are done using the pure virtual functions of this class.

It is assumed that any data structures to be filled -- such as a matrix, a vector, or simply a number -- are stored internally in the assembly kernel subclass, and that they persist between preprocessing and fill calls.

Member Function Documentation

virtual void Sundance::AssemblyKernelBase::fill	(	bool	isBC,
		const IntegralGroup &	group,
		const RCP< Array< double > > &	localValues
	)		`[pure virtual]`

Adds the results of the current integral group into the assembly results.

Parameters:

isBC	whether the current group is a replace-style boundary condition
group	the current integral group
localValues	the results of integrating the current integral group

Implemented in Sundance::FunctionalAssemblyKernel, Sundance::FunctionalGradientAssemblyKernel, Sundance::MatrixVectorAssemblyKernel, and Sundance::VectorAssemblyKernel.

virtual void Sundance::AssemblyKernelBase::postLoopFinalization ( ) [inline, virtual]

Hook to do any finalization steps after the main assembly loop, for example, doing an all-reduce on locally computed functional values.

The default implementation does nothing.

Reimplemented in Sundance::FunctionalAssemblyKernel, and Sundance::FunctionalGradientAssemblyKernel.
